Abstract

The ALLM parameterization of sigma_tot(gamma* p) has been updated by using all published F₂ data to determine its parameters. The fit yields a chi²/ndf of 0.97 for the 1356 data points. The updated ALLM parameterization, ALLM97, gives a good description of all the available data in the whole x and Q² range studied so far (3×10^-6 < x < 0.85, 0 ≤ Q² < 5000 GeV²).
